Quantifying the effects of deforestation and fragmentation on a range-wide conservation plan for jaguars

Biological Conservation, 2016
Abstract The impact of extensive changes in land use and climate on species has led to an increasing focus on large-scale conservation planning. However, these plans are often static conservation prescriptions set against a backdrop of rapidly changing environments, which suggests that large-scale information on threats can improve the functionality ...

Possible effects of habitat fragmentation and climate change on the range of forest plant species

Ecology Letters, 2002
Global circulation models predict an increase in mean annual temperature between 2.1 and 4.6 °C by 2080 in the northern temperate zone. The associated changes in the ratio of extinctions and colonizations at the boundaries of species ranges are expected to result in northward range shifts for a lot of species.

Effect of habitat fragmentation on ranging behavior of white-headed langurs in limestone forests in Southwest China

Primates, 2017
The critically endangered white-headed langur (Trachypithecus leucocephalus) is confined to fragmented karst forests of southwest Guangxi Province, China. A lack of information on the influence of habitat fragmentation on langur behavior has prevented a comprehensive understanding of their ranging behavior and the development of effective langur ...

Effects of Habitat Quality and Seasonality on Ranging Patterns of Collared Brown Lemur (Eulemur collaris) in Littoral Forest Fragments

International Journal of Primatology, 2014
Degraded forest habitats typically show low fruit availability and scattered fruit tree distribution. This has been shown to force frugivorous primates either to move further in search of food, resulting in large home ranges, or to use energy saving strategies.

Effects of Range Contraction and Habitat Fragmentation on Genetic Variation in the Woodland Deer Mouse (Peromyscus maniculatus gracilis)

The American Midland Naturalist, 2016
Abstract Recently, the range of the woodland deer mouse (Peromyscus maniculatus gracilis) in Michigan's Lower Peninsula (LP) has contracted simultaneously with the increasing abundance of the white-footed mouse (Peromyscus leucopus). The known LP range of P. m.

Fruit Availability and Peccary Frugivory in an Isolated Atlantic Forest Fragment: Effects on Peccary Ranging Behavior and Habitat Use

Biotropica, 2007
ABSTRACTThe goal of this study was to examine seasonal frugivory by two sympatric peccary species (Tayassu pecari and T. tajacu) in a small (2178 ha), Atlantic Forest fragment on the inland plateau region of São Paulo State, Brazil. Fruit availability was determined with systematic ground surveys conducted over a 5‐yr period.

Local and long‐range structural effects caused by the removal of the N‐terminal polypeptide fragment from immunoglobulin L chain λ

Biopolymers, 2003
AbstractThe role of the N‐terminal polypeptide fragment of the immunoglobulin l‐chain in V domain packing stability, and the flexibility of the whole chain was approached by molecular dynamics simulation. The observations were supported by experimental analysis. The N‐terminal polypeptide fragment appeared to be the low‐stability packing element in the

Long-range, nonadiabatic effects in statistical adiabatic channel models: Dynamic orientation of diatomic fragments formed in the decomposition of long-lived triatomic complexes

The Journal of Chemical Physics, 1990
Using the example of the decomposition of a long-lived triatomic complex into an atom and a diatom, it is shown that nonadiabatic interactions between adiabatic channel states at large interfragment distances strongly reduce the dynamic rotational orientation of the diatom.
